Multimedia Player - Video
Overview
For video, the multimedia player leverages the native HTML5 video
tag. The MPEG 4 format (H264 codec) is the minimum requirement for video because it is the standard video format on many browsers. An optional but highly recommended format, Webm (VP8 codec), should be added as well to allow some browsers such as Firefox that do not include native support for H264 to leverage the native HTML5 performance gains.
The multimedia player's timeline relies on the HTML5 progress
element and uses a polyfill when the element is not supported.
Examples
All video examples use native HTML5 video on most modern browsers including Firefox 6+, Google Chrome 3+ and IE9.
